ATTIOPNEY Patented May 30, 1933 1 UN T D STATES YORK PATENT, oFFiCE LAURIN LA KIN SEVEBECK, 0E EosELLE, NEW JERSEY, AssIGNoR T0 WESTERN ELEc I TRIC COMPANY, INCORPORATED, OF NEW YORK, N. Y., A CORPORATION OF NEW REFERENCE EILE Application filed arch as, 1932. Serial no. eoacz'sj This invention relates to visible reference files and indexes, and more particularly to removable reference elements which are frictionally held in a panel mounting.

The principal object of the invention is to provide an efficient record file having reference elements of simple and economical construction.

- In' accordance with the above object there is provided in one embodiment of the invention a sheet with weakened parallel lines between which are typed the reference data, and along. which lines the sheet is separated into. strips. Each of the strips has two spaced parallel lines press-perforated to within a predetermined distance from each end so as to provide resiliently expansible bends near the ends when the strip is folded along the partially perforated lines. The folded strips or reference elements are arranged in parallel relationship in a filing panel where they are held in place by frlction with channels ofthe panel due to the spring action of the unperforated bends at each end of the reference strip.

A more complete understanding of the in-- vention and its advantages will be had from the following description taken in conjunc' tion with the accompanying drawing, where- 1n Fig. 1 is a front elevational view of a prepared sheet from which the reference strips or elements are made;

Fig. 2 is a fragmentary-front elevational view showing a plurality of the folded index strips in position in the panel mounting to form a reference file;

Fig. 3 is a cross-sectional view taken on line 3-3 of Fig. 2;

Fig. 4C is a front elevational view of a folded reference strip or element; and

Fig. 5 is an end view thereof.

Referring now to the drawing in which like reference numerals are used to designate similar parts throughout the various views, the numeral 6 designates a prepared sheet from which the folded reference strips or elements 7 (Figs. 4 and 5) are made. The sheet 6 composed of a high rag content paper or any other suitable material, is provided with parallel perforated severing lines 8-8. 1'

Each of the strips 7 has two spaced folding lines 9 9 which are press-perforated or deeply scored to within approximately threeeighths of an inch of each end of the strip as illustrated in the upper half of Fig. 1, the unperforated distance being determined by the width of the channels 1212 of a reference file 13 (Fig. 2). v

In preparing the reference strips 7 for use in the panel 13, the sheet 6 is inserted in a typewriting machine and the desired data entered on eachof the strips 7 between the folding lines 99. The sheet is then torn along the severing lines 88 to obtain the separate strips 7 which are folded on the lines 9-9 to form the reference element illus trated in Figs. 4 and 5. Inasmuch as the folding lines 99 are closely press-perforated to within approximately three-eighths of an inch from .each end, the inwardly inclined wings 1717 of the folded strip 7 lie substantially flat or parallel to the face of the strip along the length of the perforated lines 9-9, but at their ends where the folding lines are not perforated and the fiber of the strip is unbroken, the wings 17.17 divert or flare out so that the angles of the fold are less acute and thus provide resiliently expansible bends.

By making the reference strips in accordj ance with this invention the desired spring tension is obtained only, at the ends where the strips are inserted in the channels 1212 of the panel 13 and with but two thicknesses of paper. The channels 1212 are'made with the proper depth from front to back so that when the resiliently expansible bends at the ends of the strips. 7 are compressed and inserted in the channels the strips are frictionally held in position in the panel. Also since the wings 17-17 of each strip lie substantially flat throughout the distance between the channels 12 12 there is no troublesome rippling or warping present, nor bulging which may result when the middle portion of the wings on the strip haveresiliency and spring against the face of the panel. 13 to force the middle of the strip out beyond the outer face of the channels.

Inanotherembodiment of the. invention the strips 7 are provided with the perforated folding lines 99 or heavily scored lines to 17 -.17 will lie substantially flat or parallel with the face of the strip to within the prede-.

termined distance from each end due to the weakening of the fibers of the paper, while the portions of the wings at the lightly scored folding lines 18 provideqresilient bends or folds for insertion in the channels 1212 in the filing panel 13. Hence when the folded reference strips are inserted in the panel 13 they will be retained in position due to the outward pressure of the end portions ofthe wings 1'Z17 against the inside of the channels 1212 of the filing panel.

It is obvious that the reference strips or elements 7 of this invention, which are provided with folds of the types described may be inserted,- removed or rearranged, in any type of file having channels or other suitable structure for engaging the resilient end portions of the reference strips.

l/Vhat is claimed is:

1. In a reference file, the combination of a reference element formed of a strip of materialhaving weakened lines terminating within a predetermined distance from each end of the strip and along which the strip is folded to present resiliently eXpansible bends at the ends thereof, and a mounting in which the folded strip is placed and frictionally retained'in position by reason of the resilient expansible bends at the ends of the reference element.

2. In a reference file, the combination of a plurality of reference elements arranged in parallel relationship, each element being formed of a material having weakened lines terminating within a predetermined distance from the ends of the material and along which it is folded to present resilient bends at the end thereof, and a mounting in which the folded reference elements are placed and frictionally held due to the resiliency of the bends at the ends of the reference elements.

3. In a reference file, the combination of a plurality of reference elements, each element being formed of a strip of material having weakened parallel lines terminating within a predetermined distance from the ends of the strip and along which the strip is folded to present two resiliently expansible bends at each end thereof, and a mounting in which the folded strips are placed in parallel relationship and frictionally held due to the resiliency of the ends of the reference elements.

4. In a reference file, the combination of a weakened parallel lines terminating within a predetermined distance from the ends of the strip and along which the strip is folded to present resiliently expansible bends at the ends thereof, and a pair of spaced parallel channels in which the folded reference elements are positioned and frictionally held by reason of the resilient expansible bends at the ends of the reference elements.

5. A reference element for filing purposes comprising a strip of material having a folding line weakened to within a predetermined distance from each end of the strip which is folded to provide resilient bends at the ends thereof. 1 e I 6. A filing element comprising a strip of material folded along parallel lines weakened to Within a predetermined distance from the ends of a strip to provide an area for recording purposes, and a pair of wings oppositely inclined and resiliently related to the recording area for the predetermined distance from the ends of the strip. 7. A reference strip making sheet having a series of spaced groups of folding lines, each group comprising two folding lines perforated to within a predetermined distance of each end of the sheet, and the area containing each group being separated from an adjacent group area by a severing line.

8. A'reference strip making sheet having a plurality of successive groups of parallel Weakened'folding lines, each group comprising a pair of folding lines formedby perforations spaced relatively close together and terminating at a predetermined distance from each end of the sheet, and the area containing each group being separated fromthe next group area by a weakened line running from edge to edge of the sheet for separating the sheetint'o reference strips.

In witness whereof, I hereunto subscribe my name this 14'day of March A.,D., 1932.
